sergiu Make the videos again this time don’t film the shower screen and be so close, pull back a bit, capture the group, pressure gauge and part of the lever so we can clearly see and hear what’s going on..I assume the safety sleeve is installed??
Let us know what the preinfusion settings are
I don’t think there is anything wrong with your machine at all.
P.S. If you have the flush lever, do a video using that as well.
